By some accounts, the origins of Wah Ching go back 300 years, while others date them to the mid-1960s. Whatever the case, their criminal activities are highly diversified, making them extraordinarily good at one thing in particular: making money. The Wah Ching are also violent and sophisticated, as evidenced by two 1995 raids in Los Angeles that uncovered an underground factory run by the Wah Ching featuring $18 million in counterfeit Microsoft products. The raid also found weapons and explosives, namely TNT and C-4.
